[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4A reciprocating piston nitrogen booster includes a base 1 and a booster assembly 2 disposed on the upper end of the base 1. The booster assembly 2 includes a piston 26, and a push rod 27 is fixedly connected to one side of the piston 26. A drive assembly 3 for driving the piston 26 to move is disposed on the base 1, and an adjustment assembly 4 for adjusting the movement amplitude of the piston 26 is disposed on the drive assembly 3.

[0021] It should be noted that the pressurization assembly 2 includes a pressurization tank 21 fixedly connected to the base 1. A cylinder 22 is fixedly connected inside the pressurization tank 21. Both sides of the cylinder 22 are formed with an outer expansion tube 23. The two sides of the outer expansion tube 23 are provided with slots 24. One-way valves 25 are slidably connected in both slots 24. The piston 26 is slidably connected to the cylinder 22. The push rod 27 passes through the pressurization tank 21.

[0022] In this embodiment, the one-way valve 25 consists of a sealing cap 251, an air outlet pipe 252, and a positioning ring 253;

[0023] The vent pipe 252 is slidably connected to the slot 24, the sealing cap 251 is fixedly connected to the upper side of the vent pipe 252, the positioning ring 253 is fixedly connected to the lower side of the vent pipe 252, and the vent groove 254 is provided on the circumferential surface of the vent pipe 252. A sealing gasket is provided between the sealing cap 251 and the outer expansion pipe 23. The vent pipe 252 is used for nitrogen to enter or exit the cylinder 22, and the positioning ring 253 is used to prevent it from falling off the outer expansion pipe 23.

[0024] Furthermore, the drive assembly 3 includes a motor 31 fixedly connected to the base 1, and a disc 32 is fixedly connected to the shaft end of the motor 31. The disc 32 rotates as the motor 31 rotates.

[0025] The adjusting assembly 4 includes two upright plates 41 fixedly connected to one side of the disc 32. A threaded rod 42 is rotatably connected between the upright plates 41. A connecting seat 43 is threaded onto the threaded rod 42. The connecting seat 43 is slidably connected to the disc 32. A connecting rod 44 is rotatably connected to one side of the connecting seat 43. The free end of the connecting rod 44 is rotatably connected to the push rod 27. The rotation of the disc 32 moves the connecting seat 43, thereby moving the connecting rod 44. The movement of the connecting rod 44 moves the push rod 27 back and forth. By rotating the threaded rod 42, the position of the connecting seat 43 is changed, thereby changing the movement amplitude of the piston 26.

[0026] Based on the above embodiment, an air inlet valve 28 and an air outlet valve 29 are respectively provided on the upper and lower sides of the pressure tank 21, and a sealing ring 20 is provided between the push rod 27 and the pressure tank 21.

[0027] Operating mode: During operation, connect the nitrogen container to the inlet valve 28 and the outlet valve 29 to the device that needs to input high-pressure nitrogen. Then, adjust the position of the connecting seat 43 by rotating the threaded rod 42 as needed. After adjustment, start the motor 31 to make the piston 26 move inside the cylinder 22. When the piston 26 moves forward, the upper one-way valve 25 on the front side opens to discharge high-pressure nitrogen and the lower one-way valve 25 closes. The lower one-way valve 25 on the rear side opens to draw nitrogen into the cylinder 22 and the upper one-way valve 25 closes. When the piston 26 moves backward, the state of each one-way valve 25 is reversed, thereby realizing multi-channel pressurization.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
